Существует исключение сопоставления для конкретного объекта.Не могу понять, откуда проблема возникает.Я проверил все сопоставления 3 раза от начала до конца.Тем не менее я получаю исключение Mapping.
Письмо сотруднику отображается только один раз.но все равно он сообщает об ошибке повторного сопоставления
Ошибка:
Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.cluster.entity.Email column: EMPLOYEE_ID (should be mapped with insert="false" update="false")
